To all whom it- 777/611] concern:

Be it known that I, SWAN F. Swanson, acitizen of the United States, residing at Pueblo,

in the county of Pueblo and State of Colorado,

have invented certain new and useful Improvements in Dumping-Cars; and 1 do declare the following to be a full, clear, and exact deothers skilled in the art to which it appertains toimake and use the same.

My invent-ion relates to improvements in dumping cars, wagons, and other vehicles; and it consists in the construction, combination, and arrangements. of parts hereinafter described and claimed.

The object of my invention is to improve and simplify the construction and operation of devices of this character, and thereby render them more durable and efficient in use'and less expensive of manufacture The above and other ob ects, which will appear as my invention is better understood, I accomplish by the construction 11lustrated1n the accompanying drawings, in Wl11Cl1- Figure l is a side elevation of my improved dumping-car. Fig. 2 is a vertical cross-sectional view of the same. Fig. 3 is a vertical longitudinal sectional view, and Fig. 4 is a detail bottom plan view, of one end of the car.

Referring to the drawings by numeral, 1 denotes the frame or body portion of my car, which may be mounted upon suitable trucks. (Not illustrated.) Said frame or body portion comprises two sides 2 and two upwardly and outwardly inclined ends 3. Its sides and ends are connected together and braced by suitable angle-iron bars -1 and 5, to the lowerportions of which, at each end of the frame, are secured sills 6, which are constructed of channel-iron bars, as shown. Suitable pivotbearings T sills upon their under sides, and projecting forwardly and upwardly from them are suitable draft connections 8. Each of the sides 2 consistsof a verticall'y-disposed portion 9 and an outwardly and upwardly inclined portion 10. The portion 10 may be either a solid or open-work structure: butl preferably construct it as shown in Fig. 2, the lower portion being of sheet metal and the upper portionof are provided in the center of the heavy woven wire 11. The upper portions of the sides of the body are strengthened by angle-bars 12 and 13 and are braced by in-- clined angle-irons 1H1. The sides nlay be further braced by angle-irons 15. which connect them and prevent them from spreading apart. In one or both of the sides 2 I may provide a door 16, as clearly shown in Fig. 1.

Disposed longitudinally in the center of the body of the car between the two vertical portions 9 of its sides is an invertedkshaped ridge 18, and upon each side of said ridgeis a swinging bottom gate 19. The central ridge 18 may be constructed in any suitable manner. and beneath said ridge is supported a frame 20. constructed of angle-iron, as shown.

Said frame preferably comprises two longitudinally-disposed bars 21, having their ends connected to the sills 6 and secured together at suitable points by cross-bars Said bars 21 and 22 are further connected and supported by vertical bars 23, depending from thecentral ridge 18. The bottom gates 19 comprise meta-l plates 24:, which form the bottom of the car and have secured upon their under sides cross-bars Q5 and longitudinally-disposed angle-iron bars 26. The inner ends of the bars '25 are pivotally mounted, as shown at 27, in the frame beneath the ridge 18, so that said bottom gates may swing downwardly to discharge the contents of the car. The outer ends of the bars 25 are formed with projections 28, which are adapted to support the gates in their closed position, .as hereinafter described.

In order to swing or operate the gates 19, I connect them to the frame 20 by toggle-levers 29 and 30 and provide a suitable mechanism for operating said levers. Each of the levers 30 preferably comprises two parallel bars pivotally connected at their upper ends to'one of. the bars 25 and having their lower ends pivotally connected, as at 31, to the upper end of the lever 29 and to a link 32. The lower end of the lever 29 is pivotally connected to the frame 20. The link 32 consists of two parts 33 and 3%, which are adjust-ably connected together. The. outer end of the part .31 is connected to the pivot 31, and its inner end is bifurcated, as at 35, to receive the outer screw-threaded end 36 of the part 33. Said screw-threaded end 36 extends through an opening formed in the block 37, swiveled in said bifurcated end 35, and is adapted to receive a nut 38, by means of which the parts 33 and 34 of said link may be adjusted to vary its length. The inner end of the part 33 is pivotally secured upon a crankdisk 39, which is ,here shown in the form of a gear-wheel. The toggle-levers 29 and 30 and the links 32 are disposed in pairs upon opposite sides of the frame 20, and the links of each pair have their inner ends pivoted upon opposite sides of the gears 39 at approximately diametrically opposite points, as clearly shown in Fig. 2. The gears 39 are secured upon a longitudinally-disposed shaft 40, mounted in suitable bearings in the frame 20, and meshing with said gears are pinions 41, secured. upon a longitudinal shaft 42, mounted in bearings upon the under side of the ridge 18. The shaft 42 has one of its ends extending outwardly beyond one end of the frame formed by the angle-iron bars L and 5, and upon said end of the shaft is secured a gear 43. Said gear i3 is in mesh with a train of gears 44:. mounted in suitable bearings upon one of the bars 5, the uppermost gear of said train having an operating crank-handle 4:6 secured to its shaft, as shown in Fig. 3. Said train of gears it may be disposed in a. suitable casing t7 and are adapted to be locked against rotation by a locking-pawl -18, pivoted upon the said bar 5 and coacting with the upper gear 45. It will be seen that by turning the crank 4:6 in the proper direction the gears or crankdisks 39 will be rotated to draw the links 33 toward each other, and thereby straighten the toggle-levers 29 and 30 to swing the gates 19 upwardly to their closedposition. 'hen the said crank is rotated in the reverse direction, the movement of the crank-disks 39 will be reversed to permit the toggle-levers to fold toward each other and lower the gates 19.

In order to limit the opening of the gates, l

provide chains or other flexible connections 4:9 between the frame 20 and the link 32, as seen in Fig. 2.

The bottom gates 19 are supported in their closed position by a series of levers 50, which are pivoted intermediate their ends at 51 upon the vertical portions 9 of the sides 2. The lower ends of said levers, which are normally vertically disposed, are formed with hooks 52, which are adapted to engage the projections 28 upon the outer portions of the gates. The upper ends of the levers 50 are pivotally connected together by the longitudinal bar 53, one end of which is connected by a link 5& to a depending arm 55, provided upon the transverse shaft 56, journaled in hearings in the angle-irons 1 at one end of the car.

One

of the arms 55 is formed with an upwardly and outwardly projecting hand-lever 5'5, which is adapted to be locked upon one of the bars 4: by a ratchet 58 or any other suitable locking device. It will be seen that when the lever 57 is pressed downwardly the series of ie vers 50 will be moved to disengage their lower hooked ends 52 from the projections 28 upon the gates 19 in order to permit the latter to swing downwardly to their open position. By this construction it will be seen that the gates 19 upon each side of the carmay be opened simultaneously.

From the foregoing connection with the accompanying drawings,

, theconstruction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the prindescription, taken in ciple or sacrificing any of the advantages of this invention.

Having thus described my invention. wnat I claim, and desireto secure by Letters Fatent, is-

1. In a dumping-car, tne combination of at body-frame having a central bottom ridge, swinging bottom gates hinged upon each side of said ridge, a series of toggle-levers connecting said body-frame and said gates upon ,each side of said ridge, a shaft journaled beneath said bottom ridge, crank-disks upon said shaft, oppositely disposed adjustable links connecting said crank-disks and said tog-- gle-levers, and threaded blocks for adjusting said links to vary the movement of said toggle-levers, substantially as described.

2. In a dumping-car, the combination of a bod y-frame, a swinging gate hinged upon each side of said frame, projections upon the free end of, said gate. a series of levers pivotally mounted intermediate their ends upon said body-frame and formed with lower hooked ends adapted to'engage said projections upon said gates, a bar pivotally connecting the up per ends of said levers. an operating-lever, a. link connecting said bar and said operatinglever, a series of toggle-levers for opening the. gates. gearing to simultaneously operate the toggles. links connected to the gearing and to the toggles, and threaded blocks for adj usting the throw of the toggles, substantially as described.

ln testimony whereof i have hereunto set my hand in presence of two subscribing wit nesses.
